10 Ways Humans Would Look If We Had Evolved Differently

2 Stronger People Under Stronger Gravity

As all life on Earth is adapted to the gravity level of this planet, it is interesting to think about what we would be like in a more massive world with stronger gravity. For starters, some physical aspects would not change.Humans adapted to high gravity would continue to have limbs for moving, eyes for seeing, and a mouth for feeding. They would still have hands because manipulating objects is fundamental to intelligent life-forms. But beyond these characteristics, their bodies would begin to change from ours.In a high-gravity environment, a fall from low altitude could be deadly. So, terrestrial creatures would want to be as close as possible to the ground. We can expect humans in high gravity to be short, and our current bipedal posture would no longer be efficient. Instead, an intelligent creature would walk with six legs to better distribute the weight.At the same time, there is the problem of blood pressure. In high-gravity conditions, the heart must work harder to pump blood to the head and limbs. So it is likely that people adapted to such conditions would have stronger hearts which are closer to the brain.Undoubtedly, the most visible characteristic of humans under stronger gravity conditions would be a higher bone and muscle density. Their bones would be thicker to support the body structure, and their muscles would be bigger to be able to move without much effort.Studies in animals also suggest that humans in this extreme environment would have a much lower amount of body fat than humans on Earth.[9]
